Evidence at a crime scene, such as blood, DNA, fingerprints, or shoeprints all help forensic investigators determine what might have occurred and help identify or exonerate potential suspects.…
In 1892, Francisca Rojas was found with intense neck injuries while her two sons were found with their throats cut open and dead. Francisca Rojas fanatically accused her neighbor who, under extreme interrogation, would not confess of committing murder and injuring Rojas’s neck. Inspector Alvarez, the head of the case, went to the crime scene and found a bloody fingerprint next to where the boys laid. After comparing the fingerprint to those of the neighbor, mother, sons, and other suspects, Alvarez deduced that it matched the mother’s right thumbprint. She then confessed to the murdering of her sons. The discovery of the print saved an innocent neighbor from harsh punishment. Fingerprints help solve crimes and save people's lives everyday. For that reason, it is important for people to understand fingerprints significance.…
3. Police officers, crime scene investigators and others in the justice system rely on forensic science techniques to ensure that the right people are punished for law violations and to keep people safe. Fingerprints are starting players in the criminal offense and defense lineup. They are so important to criminalistics that justice officers still use fingerprint systems over a hundred years after scientists developed them.…

Introduction:Dna evidence has been known for many years in crime scenes.Dna evidence was first discovered in 1986.Dna evidence can find anyone by finding blood,skin cells,hair,saliva,and semen.Dna evidence can be good at finding people 95% at a time,because of the cells in the dna.…
2. Forensic science has been increasingly used by the criminal justice system because of its growing accessibility. Technological advances over the last hundred years have made methods such as finger printing, blood and DNA analysis, and other forms of identification much easier for forensic scientists to perform, thus paving the way for the development of this field. Similarly, there has been an increased popularity for…
First, DNA can solve criminal cases.it could help police to investigate crimes some people think that DNA fingerprinting is very accurate, and it also is very sensitive and can be contaminated easily. But DNA test results are much clearer than fingerprints and it is with these results can proofs that it is possible…
After DNA samples are loaded into the sample wells, they are forced to move through the gel matrix. What size fragments (large vs. small) would you expect to move toward the opposite end of the gel most quickly Explain. 9.…

These days, fingerprinting people seems pretty cunning. With a DNA database, fingerprints seem like a reliable source. For example, if a homicide were to occur and investigators found five peoples difference fingerprints close to the scene, unskilled jurors may think the prints are associated with the crime, and accuse all five people guilty. The jurors would need more evidence to actually, by law, accuse a person, or people guilty of a crime, rather than just finger prints.…
Is there a better way of solving crimes with DNA evidence to help investigators? The use of DNA technology is the best way to solve investigations. DNA makes it possible to identify people and to know who was at the crime scene based on a little piece of evidence. It helps solve crimes, and even, open cold, unsolved cases. DNA technology in criminal investigations has become an essential tool because of its ability to identify culprits through the use of fingerprints, blood, and genetic samples.…
The use of DNA technology has increased the probability of finding the culprit and also prevents further crimes. Compared to the past, with DNA technology, today “more than twice as many suspects are[were] identified, twice as many suspects are[were] arrested and more than twice as many cases are accepted for prosecution” (Ritter, 2008). This is because of higher availability of DNA sources and uniqueness of DNA. Between two people, 99.9…
To begin with, DNA can be used to solve a crime. Investigators utilize DNA analysis to match suspects to crime senses, samples can be polluted with DNA from other sources.…
In our day to day activities, we are surrounded by science. In our lives, science plays an extreme role. DNA is the abbreviation for Deoxyribonucleic acid. It is present in all organisms, whether it is a bacteria, bird or mammal. DNA is a long molecule that carries a particular genetic data; it is located in every cell in a human body except the red blood cells. DNA profiling is easy acquire and very accurate in identifying a person. There are many different ways a forensic expert or a police officer can get DNA samples. In criminal cases, DNA samples help solve many crimes. However, it also releases innocent people from prison. DNA is known to be he best thing that happened to forensic science since the advent of finger printing.…
